Ethereum Foundation researcher discusses the economic impact of the max-blobs flag: Local builders or prioritizing stability

Wu learned that Ethereum Foundation researcher @nero_eth discussed the economic impact of the max-blobs flag. There are significant differences among builders in the use of blobs: some builders use them hardly at all, while others avoid adding them due to high transaction costs, particularly MEV-Boost builders who rely on relays and optimization tools typically do not adopt blobs extensively. As a result, local builders often propose blocks that include 6 blobs, which can cause bandwidth peaks and increase the risk of reorganization, while also imposing higher demands on the hardware and bandwidth of validators, potentially affecting the participation of "home stakers." The max-blobs flag allows local builders to limit the number of blobs within a block, thus better controlling the data load. Although this sacrifices some fee revenue, the losses are relatively low compared to overall earnings and are suitable for those local builders with high reorganization rates who do not rely on MEV-Boost and place greater emphasis on block propagation efficiency and stability. It is understood that the current blob target and maximum for Ethereum are 3/6, which will be adjusted to 6/9 after the Pectra upgrade.
